Thaum engineers nyob rau hauv hydraulic system OEMs los yog oilfield service tuam txhab uas muag nrhiav rau ib tug Tuam Tshoj hlau casting Hoobkas, lawv tsis nrhiav tus nqe lus qis tshaj. Lawv tab tom tshawb nrhiav qhov rov ua tau zoo dua ntawm cov cobalt alloy twj tso kua mis vaj tse, metallurgical sib xws thoob plaws 50 AMS 5387 castings, lossis xoom surprises thaum T800 winch ncej ua tsis tiav nws qhov kev sim hydrostatic. Peb tau pom nws ntau zaus: ib qho "tsim nyog" qhov chaw tsim khoom xa cov khoom uas dhau los ntawm kev kuaj pom - tab sis tawg hauv qab 300 bar siab cycling vim tias cov qauv nplej tsis tau txheeb xyuas, lossis qhov tawv tawv tawm sab nraud spec tom qab kev kho cua sov.
Kev ntseeg hauv ntiaj teb tiag tiag pib nrog kev ua tswv cuab-tsis yog outsourcing
Cov neeg yuav khoom thoob ntiaj teb feem ntau xav tias casting thiab machining yog cov kev pabcuam cais. Qhov kev xav ntawd ua rau muaj kev pheej hmoo. Thaum casting ua tiav nyob rau hauv ib qho chaw, kev kho cua sov hauv lwm qhov, thiab CNC ua tiav nyob rau hauv ib feem peb, qhov hloov pauv tseem ceeb-xws li residual stress distribution los yog microstructural teb rau thermal cycling-slip los ntawm handoff gaps. Ntawm QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., tag nrho peb theem tshwm sim hauv ib lub ru tsev ISO-certified hauv Qingdao. Qhov no tsis yooj yim - nws yog tswj. Peb cam khwb cia hlau twj tso kua mis lub hauv paus, ces tshuab nws mounting flange thiab chaw nres nkoj ntsej muag nyob rau hauv tib lub teeb, siv tib CMM-calibrated tooling. Tsis muaj re-fixturing. Tsis muaj kev hloov pauv. Tsis muaj kev kwv yees txog yuav ua li cas cov casting qhov kev cuam tshuam li cas yuav cuam tshuam qhov kawg GD&T ua raws.
Peb tau validated no vertically integrated qauv ntawm ntau tshaj 127 hydraulic valve tej yaam num. Ib tus neeg siv khoom North American tau hloov pauv los ntawm tus neeg xa khoom tier-1 tom qab rov ua qhov tsis ua tiav ntawm lub rooj sib tham. Lawv lub hauv paus ua rau kev tsom xam pom qhov tsis sib haum xeeb microhardness gradients hauv lub valve lub cev bore - tshwm sim los ntawm kev tswj tsis tau txias ntawm cov casting thiab tom qab kev kho cua sov. Peb qhov kev daws teeb meem? Cam khwb cia lub cev, ua cov tshuaj annealing * hauv tsev *, tom qab ntawd ua tiav-dhau lub rooj zaum hauv 48 teev-ua ntej ambient ya raws lossis tuav tuaj yeem qhia oxidation saum npoo. Qhov tshwm sim: xoom xau hauv 18 lub hlis ntawm kev ua haujlwm hauv thaj chaw thoob plaws 42 cov khoom siv sab nrauv.
Tsis yog txhua tus cobalt alloys coj zoo ib yam - thiab tsis ua cov chaw ua haujlwm uas ua rau lawv
AMS 5387 cobalt alloy tsis yog "nyuaj rau tshuab." Nws cov carbide nag lossis daus tus cwj pwm hloov pauv ntau nrog txawm tias 0.3 ° C sib txawv thaum lub sij hawm muab tshuaj annealing. T800 alloy xav tau meej preheat ramp tus nqi ua ntej vuam kho - txwv tsis pub, intergranular cracking tshwm sim thaum kawg NDT. Ntau tus neeg muag khoom kho cov ntaub ntawv no ua "superalloys". Peb kho lawv raws li kev ua neej nyob nrog cov keeb kwm thermal.
Peb cov khoom siv traceability raws tu qauv mus dhau daim ntawv pov thawj zeb. Txhua lub tshav kub muaj ib tus ID tshwj xeeb txuas rau cov cav ntoo, tua cov ntaub ntawv xov xwm kub, thiab tom qab cua sov-kho hardness daim ntawv qhia hla peb ntu ntu. Thaum lub tuam txhab European lub twj tso kua mis xav tau 22 lub taub hau nrog Rockwell C 42-46 hardness * thiab * 100% ultrasonic huv, peb tau khiav lub tshuab cua sov, kho lub sij hawm ntub dej los ntawm 9 feeb, thiab rov ua dua hardness profiling-ua ntej cog lus rau ntau lawm. Qhov theem ntawm iteration tsuas yog ua haujlwm thaum metallurgy, casting, thiab QA zaum hauv tib chav.

Kev xa khoom tseeb tsis tau cog lus tseg - nws tau tsim kho
"Lub sijhawm ruaj khov" txhais tau tias muaj ntau yam sib txawv rau tib neeg. Rau pawg neeg yuav khoom, nws txhais tau tias tsis muaj nqi thauj khoom huab cua kawg. Txhawm rau tsim cov engineers, nws txhais tau hais tias tau txais thawj-kab lus * nrog tag nrho cov ntaub ntawv soj ntsuam * - tsis yog cov ntaub ntawv loj xwb, tab sis cov duab microstructure, daim duab qhia kev nyuaj, thiab tshuaj xyuas qhov chaw - ua ntej kos npe rau ntawm PPAP.
Peb tsim kev xa mus rau hauv tus txheej txheem - tsis nyob ib puag ncig nws. Kev npaj tsim khoom siv takt-time sequencing, tsis yog batch-and-queue logic. Yog hais tias lub piston twj tso kua mis lub tog raj kheej vaj tse yuav tsum tau 3 kev kho cua sov, 5 machining setups, thiab 2 nto finishes, cov kauj ruam yog teem rau nyob rau hauv tas li ntawd raws li lub sij hawm tsis tau faib * nkaus xwb * rau kev txheeb xyuas tsis ua hauj lwm hom - tsis theoretical qeeb. Peb cov khoom xa tuaj raws sij hawm nruab nrab rau cov xaj nruab nrab (50-500 pcs) sawv ntawm 98.7% hauv 22 lub hlis dhau los. Qhov sib txawv ntawm 1.3%? Tag nrho cov taug qab mus rau cov neeg siv khoom thov kev hloov pauv engineering tom qab pwm tso tawm - tsis yog kev ua haujlwm sab hauv.
Xaiv lub Tuam Tshoj hlau casting Hoobkas tsis yog hais txog geography - nws yog hais txog kev sib raug zoo
QINGDAO QIANGSENYUAN TECHNOLOGY tsis ua haujlwm rau txhua qhov kev lag luam. Peb tsom mus rau cov ntawv thov uas tsis ua haujlwm muaj qhov tshwm sim tiag tiag: hydraulic siab li qub tswj excavator boom txav, cobalt alloy plugs sealing high-H2S gas manifolds, winch center ncej rollers lifting subsea khoom hauv 3,000-meter dej tob. Qhov kev tsom xam tsav txhua yam - los ntawm peb cov khoom muag khoom vetting (peb tshawb xyuas lub tshuab hluav taws xob ntsuas lub cav peb lub hlis twg) rau peb CMM sojntsuam xaiv (Renishaw PH20 nrog 5-axis scanning rau complex impeller contours).
Yog tias koj qhov project tom ntej no yuav tsum tau rov ua dua microstructure hauv cobalt-based castings, GD & T-raws li machining ntawm hardened nto, los yog tag nrho traceability mus rau lub tshav kub ntau - thiab koj xav tau nws xa tsis tau engineering hluav taws xyaum - ces txoj cai Tuam Tshoj hlau casting Hoobkas tsis yog ib qho uas muaj ntawv pov thawj tshaj plaws ntawm phab ntsa. Nws yog ib qho uas kho koj cov duab kos raws li kev ua haujlwm tshwj xeeb, tsis yog kev tawm dag zog geometry. Nws yog tus khub uas nug * ua li cas * qhov chaw thauj khoom, * qhov twg * nws kaw, thiab * yuav ua li cas yog tias nws ua tsis tiav * - ua ntej hais ib xees.
